[BProc] RE: libraries are missing in /lib on the slaves

[Larry B. <ba...@us...>]

The web manual for BProc (http://bproc.sourceforge.net/x86.html) talks =
about a modified dynamic linker that fetches libraries not found =
locally.  I assume this does not help find missing libraries during =
compilation, only missing libraries at run-time.  I modified Intel's =
make_exe makefile to compile on the master and run the BLAS tests on =
slave 0, which is how I plan to use the cluster anyway.  This worked.

FYI: execution times from my (uniprocessor) Fortran finite-difference =
code:

   Compaq Alpha DS20E 667 MHz
      Tru64 Unix 5.1, Compaq Fortran "f90 -fast":  4.93 seconds.

   Intel P4 1.8A w/ \/IA chipset and DDR2100
      WNT4/WS, Microsoft Fortran PowerStation "/Zi /G5":  5.14 seconds.
      Red Hat Linux, g77 "-O3 -funroll-loops":  5.34 seconds.
      Red Hat Linux, Intel Fortran (default options):  4.45 seconds.
      Red Hat Linux, Intel Fortran "-O2 -ip -pad -tpp7 -xW":  4.14 =
seconds.
      Red Hat Linux, Intel Fortran "-O3 -ip -pad -tpp7 -xW":  4.15 =
seconds.

   Apple G4 867 MHz
      OS 9, Absoft Fortran "-O":  13.89 seconds.

We have yet to test and code that uses the Intel BLAS library routines.
